of Minnesota, .have invented a new 'and'Imf proved Seed-Planter, ofwhich tlieollovv-'- v to vagricultural 'im-- My invention relates a plurality of seeds plements for dropping- .at a given .distance apart in a row, andthe.

inventionis especiallyr intended for ernbodiment in an implement for 'planting' sugar beets and like 'plants, whichf are usuallyplanted in continuous rows, -`and the plants-have grewnto a;

considerable4 height, are thinned out by a chopper.

Anobject. of my invention is to provide 4an implement yv vhlch'will be vso eilicient lin action as. todrop the :seeds in sufficient number andfa-tfsuch ldistances"apar-tas to avoid thefwaste off v seed and laborin` subsequently chopping out the supe'ruous plants. v
